If I had a pipe that was 240,000 miles long, one end in the ocean, the other end on the surface of the moon would liquid water be pulled through the pipe such as I can with a soda straw here on Earth

Water would not be pulled out.
The force that moves the water up the pipe is the weight of the atmosphere pushing not the vacuum sucking. (one can also desciube this as atmospheric pressure - which again is the weight of the atmosphere)
when you create a vacuum in a pipe by sucking - you are removing the balancing pressure in the pipe - reducing the impedance. Thus the weight of the atmosphere pushes the water up or along the pipe. How far up the tube depends on how strong a vacuum you create - up to a maximum height given by how hard the atmosphere pushes against the total lack of pressure of a vacuum. That maximum height is about 33.9 feet.
this is the reason that a shallow well pump can only pull water up a certain height (usually about 25 feet as it cannot create a perfect vacuum). when you want to go deeper you use a deep well injection pump - that pushes water down the pipe to draw more up. ie. one can create pressure above atmospheric pressure - but of course the minimum pressure is a vacuum.

Hi. No. A straw works by the difference in air pressure between the atmosphere and the partial vacuum of your mouth. It can only lift the water about 30 feet.

the pipe may collapse due to atmospheric pressure before it can suck up the water.
try covering one end of a straw and sucking on the other.
then you can see just what i mean.
gravity will over come vaccum.
what you see in movies is valid,but when you're in a space ship, the gravity if any, is less than what we have on Earth
God bless,

No. If the vacuum of space was stronger than Earth's gravity, we wouldn't have an atmosphere!

Go back and see what is the highest that u can siphon water over and understand what it means. It is gravity that is pulling not the vacuuming of space.

you seem to be confusing "the vacuum of space" with the hoover
vacuum in you're house. the "vacuum" in space is the total absence of atmosphere, no plus, no negative. wherein a hoover
needs atmosphere to operate. space, without a gravitational body
is just that, nothing. good question though.

No it wouldn't work, as others have explained. But thank you for not posting an idiotic question like a lot of people do.

No, but the pipe might be flung into space..

No, otherwise the Earth would not even have an atmosphere.

to understand the power of infinate power is dwarfing any finite explanation. no one belives it til it happens
